메자닌 상품은 채권과 주식의 성격을 모두 가진 금융 투자 상품인데 주로 등급이 낮은 회사가 유동성을 확보하기 위해 금융시장에서 발행한다. 따라서 메자닌 상품에 투자하는 사채권자들은 해당 회사가 발행하는 메자닌 상품에 투자하면 주식으로 전환하는 여부와 함께 주식으로 전환하고자 하는 시점에 대해서 의사결정을 해야 한다. 예컨대 메자닌 상품의 투자자와 발행회사는 투자자의 전환권 행사 여부와 시점에 대한 의사결정 문제가 가장 중요한데 이를 위한 투자 판단 지표가 매우 부족하므로 직관적이거나 정성적인 판단에 의존할 수밖에 없다. 따라서 본 논문에서는 주요 업종별 주식 전환 행사가 완료된 총 2,000개의 학습 데이터와 200개의 예측 실험 데이터로 구분하고 인공신경망 모델을 통해서 메자닌 행사 알고리즘을 설계하고 성능을 분석한다. 본 주제는 금융 분야에서 관심이 높은 메자닌 상품 행사의 난제를 인공신경망 기술을 적용하여 과학적으로 해결하는 방법론을 제안했다는 점에서 그 의의를 갖는다.

This paper applies a structural technique with uniform parallel switch characteristics in gates and power loops to minimize the ringing and current imbalance that occurs when a general discrete package (TO-247)-based power semiconductor device is operated in parallel. Also, this propose a heat sink integrated switching module with heat sink design flexibility and high power density. The developed heat dissipation-integrated switching module verifies the symmetry of the parasitic inductance of the parallel switch through Q3D by ansys and the validity of the structural technique of the parallel switch using the LLC resonant converter experiment operating at a rated capacity of 7.5 kW.

본 연구에서는 우리 나라 현 개발금융의 현황과 문제점을 살펴보고, 지역개발사업의 확대를 위한 개발금융 활성화 방안을 모색하였다. 지방자치제 이후 지역경제를 활성화하기 지역개발사업에 대한 관심이 증가하고 있는데, 이러한 지역개발사업의 확대를 위해서는 개발금융의 활성화가 필요하다. 그런데 현 개발금융의 실태를 보면, 개발기능이 영세하고 미분화되어 있으며, 제조업 위주의 금융작원 배분으로 제도권 금융시장에의 접근성이 낮으며, 기업금융 방식이 지배적이어서 사업금융이 발달하지 못하였으며, 자본시장의 활용이 미비한 등의 문제점이 나타난다. 이러한 맥락에서 개발금융의 활성화하기 방안으로, 격려로 부동산 지분투자펀드의 활용 방안, 둘째로 프로젝트 파이낸싱의 활용 방안, 자산담보부증권의 활용 방안, 넷째로 메자닌 캐피탈의 활용방안을 도출하였다.

Except the time when relics of a museum are exhibited or loaned to the public, they are stored in a storage. In addition, it is common view that collections are exhibited a few of total stored collections in a museum. Therefore, the environmental condition of a storage is an important factor. Hereby, the purpose of this study is to suggest the design guidelines of a storage for conservation of relics in a museum. The results from this study are as follows briefly. First, location of storages has to be located and centralized above ground against preservation environment and additional renovation. Second, for storage size, It is reasonable to secure long-term experimental data after planning about 20% of whole section in present domestic situation. Third, in order to prevent environmental deterioration due to short storage floor space, adequate storage height has to be secured against a mezzanine deck and spare storages need to be planned. Where a mezzanine deck is designed, detailed plans have to be supported for equal micro climate in a storage. Fourth, in respect of environmental control of storages, finish materials with adjustment ability on relative humidity have to be used after the system is installed jointly direct and indirect way by air chamber, considering domestic condition for management of intermittent ventilation.

This paper deals with the development of warehouse layout design algorithm. In the developed model, receiving/outgoing areas, storage areas, picking/distribution areas, value-added operation areas and support areas are considered. For more efficient use of the warehouse floor space, a mezzanine floor is also considered. We develop heuristic algorithms of warehouse layout design for several cases: three types of warehouse and three types of flow. This study is expected to be used as a guideline in warehouse layout design phase.

The purpose of this study is to provide the guidelines for the planning and design of officetels, meeting the requirements of life in one-person household which is a new type in housing market. Literature survey is used as a research method. We analyzed the needs of officetel residents, by reviewing researches and by examining internet homepages and catalogs of 20 officetels sold since 2000. Case study analysis method is used as a qualitative analysis. The major findings of this study are as follows; 1) In dwelling unit space, it lacks the independence of working space and the privacy of living space. Therefore, the provision of various unit plans, such as 2-bay plan, unit with mezzanine floor or movable walls, layout of kitchen and dining area in window side, is proposed. 2) In communal space, it lacks the consideration of natural environments and the systematic maintenance. Therefore, the introduction of communal workshop and conference rooms and of various types of garden space, is proposed.

The aim of the present contribution is to consider and underline the essential interactions among the historical knowledge, the seismic vulnerability assessment, the investigation experimental tools, the preservation of the architectural quality and the strengthening design in regard to architectural heritage conservation. These topics are argued in relation to Palazzo Murena in Perugia, designed in the eighteenth century by the famous Architect Luigi Vanvitelli, and currently headquarters of the city's University. Based on the surveys and the visual inspections, a preliminary a priori global analysis has been performed by means of the FME method. The obtained results permitted to plan an experimental tests campaign inclusive of structural health monitoring. The new achieved "knowledge" of the building allowed to refine the seismic safety assessment. In particular it was highlighted that the "mezzanine floor" can be a vulnerable element of the building with the collapse of its masonry walls. Preserving the architectural characteristics, a local reinforcement intervention is proposed for the above-mentioned level; this consists of the application of plaster with FRCM, assuring an adequate strength, without burden the masonry structure with additional weight, and therefore a decreasing of the seismic vulnerability. The necessity to consider, in this ongoing research, other local mechanisms is highlighted in the unfolding of the last part of work.

The purpose of this study is to propose the unit plan for home office which can substitute the existing unvaried unit plan in housing and homogeneous working space in office building through the recognition of necessity and possibility about whether home-basedworkandhomeofficecanbeformedornot. Based on the above contents of a research, the following conclusions were summarized; 1. The unit plan of home office was divided into 'jointly-used type' and 'independent-separated type' in accordance with the relationship between housing and working space, 'dwelling-emphasis type' and 'working-emphasis type' in accordance with the grade of ranks between housing and working space. And the universal validity which could accept properly the dweller's characteristics was drawn by the above classification of unit types. 2. The required characteristics in a unit plan for home office were classified into flexibility, privacy, efficiency, identity, amenity. And the analyzing system of planning methodology was assigned according to dividing interior components into space-functional, space-designing interior facts. The planning methodology would have to be considered on the correlation with each required characteristic. As a result of the study, through a planning of independent-separated type, In especial, 'vertical-separated type', it was certificated that vertical-separated type could satisfy a variety of required characteristic in space-designing as well as space-functional aspect.

본 연구에서는 자동이체증권과 세 가지 CMO(collateralized mortgage obligations)를 대상으로 MBS(mortgage-backed securities) 발행구조와 가치를 이론적인 모형으로 고찰하였다. 모기지의 조기상환 위험 중 단축 위험과 연장 위험을 모두 모형에 반영하고, 다양한 유형의 CMO를 포함하기 위하여 TAC(targeted amortization class)과 같은 중순위 트랜치를 포함하였다. 연구 결과 평이한 발행 구조의 자동이체증권의 효용이 가장 작고, PAC-TAC-Support 트랜치로 구성된 CMO의 효용이 가장 크며, 모든 유형의 CMO에 있어 투자자 효용을 최대화하는 최적의 구조설계가 내부해(interior solution)로 존재함을 발견하였다. 이처럼 MBS의 기초자산인 모기지풀에 내재된 위험의 크기가 고정되어 있어도 MBS의 다양한 트랜치에 이러한 위험을 집중 및 제거하여 효율적으로 재분배할 때 위험회피적 투자자에게 새로운 효용이 창출될 수 있다. 또한 본 연구 결과는 단순한 혹은 극단적인 선순위-후순위채 구조보다 다양하고 절충적인 선순위-중순위-후순위채 구조가 선호되며, MBS를 효과적으로 발행하기 위해서는 투자자 효용에 대한 체계적 연구가 필요함을 시사한다.
